SUPPORT FOR SLATERS.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed August 6, 1906. Serial No. 329,303.

To all whom it may concern:

Be it known that I, FREDERICK F. HASKELL, a citizen of the United States of America,.and a resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Supports for Slaters, of which the following is a specification.

This invention relates to roof brackets and particularly to those for supporting a platform for the use of slaters operating upon the roof of a building.

It has for its object the simplification of devices of this kind while at the same time their efiiciency is greatly increased.

The invention consists in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings: Figure 1 represents a side elevation of the improved bracket shown as applied to a section of a roof. Fig. 2 represents a front elevation of the same. Fig. 3 represents a plan of the same. Fig. 4 represents an elevation of the securing end of the roof member. Fig. 5 represents a detail of the bifurcated locking device secured to the roof member. Fig. 6 represents a perspective view of the end of the platform support adapted to engage with said locking device, drawn to an enlarged scale, and Fig. 7 represents a perspective view of a portion of the vertical support showing the brace-engaging hook.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 represents the platform support formed of two plates 11 riveted together at 12 and 13 and separated at the rear to form the fork 14, the ends of which are pivoted at 15 to the upright U-shaped member 16. The support 10 has pivoted thereto at 17 the brace 18 the outer end of which is provided with an eye or opening 19 adapted to engage the hooked lug 20 struck up from the side of the member 16, as shown clearly in Fig. 7. I

The support 10 is provided on its upper edge with a plurality of spurs 21 adapted to engage the platform 22 shown only in dotted line to prevent it from moving on said support 10. The free end of said support 10 is provided with outwardly projecting lugs or ears 23 adapted to enter slots in the bifurcated member 24 secured to a flat strip 25 adapted to lay fiat upon the slates 26 attached to a roof 27 in the usual manner. The free end of the support 10 enters the groove formed between the upturned parallel sides 28 of the bifurcated member 24, the outwardly extending ears 23 of said support entering the slots 29 therein, thereby locking the platform support rigidly in position. The platform support 10 is also provided with laterally projecting spin's 30 which engage the outer edge of the bifm'cated member 24 and assist in more firmly locking the platform support and bifurcated member together. The pivot 15 is so situ ated relative to the end of the platform support that the corner 31 thereof prevents the cars 23 from being lifted unless an opportunity is given for the upright or vertical member 16 to yield slightly to permit the raising of the ears 23 in the slots 29 which is prevented when the brace 18 is locked in position. The lower end of the vertical member 16 is pivoted at 32 to a U-shaped member 33 riveted at 34 to the lower end of the roof member 25.

The upper end of the roof member 25 is provided with bayonet slots 35 which are adapted to engage nails 36 driven into the roof 27. In the operation of the device the slaters lay slates as far as they can reach from their platform and then place the device in position upon the slates already attached to the roof with the slotted end thereof just immediately above the upper edge of thehighest course of slates and drive nails 36 through the slots therein to secure the bracket in its new position.

When the new bracket has been located and the slaters have secured positions thereon a new course of slates are laid above those already laid and over the nails, seciu'ing the roof member to the roof. When it is again desired to change the position of the platform the nails are left in position beneath the slates and all that is necessary to make the change is to move the roof member upward in the direction of the arrow (1 shown in Fig. 2, and then in the direction of the arrow b in the same figure, thereby disconnecting the roof member from the nails 36 so that it may be withdrawn for use in a new location. When not in use the bracket may be folded by disconnecting the brace 18 from the hook 20 and unlocking the support 10 from the bifurcated member 24 and folding the support 10 into the interior of the U-shaped support 16 and permitting this member to move about its pivot 32 into contact with the roof member 25, the bifurcated member 24 entering the spaces between the side walls of the U-shaped vertical member 16.

It is believed that from the foregoing, the operation of the invention will be thoroughly understood without any further description.

Claims.

1. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said roof; a vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; a pair of parallel lugs provided with inwardly extending slots, said lugs projecting from said roof member; and lateral ears on said platform support engaging said slots when said support is inserted between said lugs.

2. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said roof; :1 vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; parallel lugs projecting from said roof member each provided with a transverse slot; lateral ears on said platform support engaging said slots when said platform support is positioned between said lugs; and means for preventing the disengagement of said ears from said slots.

3. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said roof; a vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; slotted lugs projecting from said roof member; lateral ears on said platform support engaging said slots; and a locking device interposed between said platform support and vertical member for preventing the disengagement of said ears from said slots.

4. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said root; a vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; bifurcated member having slots therein the side wallsthereof being secured to and projecting from said roof member; and lateral ears on said platform support engaging said slots.

5. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said roof; a vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; parallel lugs projecting from said roof member each provided with a transverse slot; lateral cars on said platform support engaging said slots; and other ears thereon engaging the edges of said lugs.

G. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said roof; a vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; a bifurcated member secured to and projecting from said roof member provided with slots ex tending through the side walls of said member and to one end thereof; and lateral ears on said platform support engaging said slots. v

T. In a roof bracket, the combination of a member adapted to rest upon the roof; means for securing the same to said roof; a vertical member pivoted to the lower end of said roof member; a platform support pivoted to said vertical member; a bifurcated member secured to and projecting from said roof member provided with slots extending through the side walls of said member and to one end thereof; lateral ears on saidpplatform support engaging said slots; and other ears thereon engaging the edges of said lugs.
